In the Forum of December, 1889, p. 455, the same writer describes his experience at the house of a friend with whom he had been acquainted eight or ten years. When about to depart, he thought he would try an experiment. He says:--
"She and I stood at opposite ends of the table at which we had been sitting. Both of us having placed the tips of our fingers lightly on the top of the table, I spoke, as if addressing some unseen force connected with the table, and said: 'Now I must go; will you not accompany me to the door?' The door was ten or fifteen feet distant, and was closed. The table started. It had no casters, and in order to make it move as it did, we should have had to go behind and push it. As a matter of fact we led it, while it accompanied us all the way, and struck against the door with considerable force."
